High quality and high yield

In recent years, aquatic vegetables such as Chinese wolfberry have developed rapidly. Some free-flowing floodplains and shallow ponds, especially some low-lying fields, have been planted in the wild, and white crops have become a good way for farmers to increase their income. However, most farmers do not attach importance to management, and in particular do not pay attention to post-harvest management. Reasonably, the winter planting fields in Putian will have light pests and diseases in the coming year, with neat crop emergence, many tillers, thick seedlings, few grey plants and male plants, and high yield and high quality.
After clearing the white fields of Putian, we should promptly excavate the plants of the ashes and maggots in the field, and cut the old leaves of the old plants on the old quayside, and pile the old leaves together to burn them. This will reduce the number of overwintering pests and diseases, and the buds will be neatly cut, and the new seedlings grown in the second year will be thick.
After drying, the plants gradually entered the dormant stage after harvesting, and the above-ground nutrients gradually transferred to the underground rhizomes. At this time, sufficient oxygen was needed to supply the soil to promote the growth of winter shoots on the underground rhizomes and stems. Therefore, after harvesting, dry field water should be used to dry the field, and after the fine cracks on the field surface, the water should be rehydrated. Rehydration is carried out before the onset of frost, generally maintaining a water level of 2 to 3 centimeters. After December, it can deepen the water level to 7 to 10 centimeters to protect the underground rhizomes from wintering safely. The weather turned fine in early March and the water level dropped to 2 to 3 cm.
Scientific fertilization between the cold and the beginning of spring, per acre Shiren familiar livestock and manure 4000 kg, in order to ensure the quality of fleshy stems, not stiff. Base fertilizer application can not be later than the beginning of March. After the beginning of spring, about 20 cm in height, the combination of cultivating and weeding, applying 25-30 kg of urea per mu or 40-50 kg of ammonium bicarbonate, to promote the germination of new shoots.
The seedlings of the seedlings in the late winter and early spring of the complementing seedlings and seedlings at the beginning of the spring period are checked as soon as possible when the seedlings of the old seedlings germinate. Where there are no piers, the new seedlings to be cut and germinated will be made up. Too many germinating seedlings on the old loquat piers should be cleared, and some weak and weak seedlings must be removed.
